The Siege of Boston (April 19, 1775 – March 17, 1776) was the opening phase of the American Revolutionary War, in which New England militiamen—who later became part of the Continental Army—surrounded the town of Boston, Massachusetts, to prevent movement by the British Army garrisoned within. After eleven months of siege, the American colonists, led by George Washington, forced the British to withdraw by sea.
The Battle of Brandywine was fought September 11, 1777, during the American Revolution. Landing at Head of Elk, Gen. Sir William Howe marched north with the goal of capturing Philadelphia. Opposed by American forces at the Battle of Brandywine, the British won clear victory after turning the enemy flank.
